SUSTAINING SUPPORTING PROP FOR DISPLAY MOUNTS Oct. 3, 1961 SELF- 2 Sheets-Sheet 2 Filed Jan. 5, 1961 INVENTOR.

This invention relates to display mounts and to the method of making display supporting assemblies for such mounts.

t is the object of the invention to provide a display mount structure which is simple to fabricate and which embodies a unique display supporting assembly.

In its most specific aspect, the display mount herein comprises a display supporting assembly which consists of'a display mounting section made up of a pair of equal sized panels one of which is infolded into face-to-face contact with the other, and a supporting prop section which is also made up of a pair of equal sized panels one of which is infolded into face-to-face contact with the other. The two sections of the display supporting assembly are separated from each other by an interrupted hinge slot and the free edges of the infolded panels coincide with the respective edges of the sections Which define the hinge slot. A hinge plate of ductile material is disposed between the folded sections such that it bridges the hinge slot. A display holding assembly is hinged at one of its edges to an edge of the display supporting assembly by. an adhesively attached flexible binding material extending over a face and about the edges of the assemblies whereby the assemblies themselves are also bound together.

The display supporting assembly is particularly designed to lend itself to fabrication by machine methods and to this end, the method of making the display supporting assembly comprises the steps of forming a transverse hinge slot in a generally rectangular blank of paperboard whereby the blank is divided into the supporting prop section at one side of the hinge slot and the display mounting section at the other side of the hinge slot. As the hinge slot is being formed, the sections of the blank are transversely scored along lines parallel to the hinge slot whereby the supporting prop section is divided into a supporting prop face panel and a supporting prop back panel of equal size and whereby the display mounting section is also divided into a display mounting face panel and a display mounting back panel of equal size. A hinge plate holding tongue is simultaneously formed in the display mounting back panel such that the free end of the tongue projects toward the hinge slot. The hinge plate is now assembled with the blank such that it overlies the hinge slot and an edge thereof is engaged under the hinge plate holding tongue. Thereafter the supporting prop face panel and the display mounting face panel are folded inwardly into contact with the hinge plate whereby the plate is sandwiched between the respective panels. The display supporting assembly is completed and connected to the display holding assembly by adhesively attaching a flexible binding'material to the assemblies such that it covers the infolded surface of the assemblies and extends about the edges thereof.

Other features of the invention will be pointed out in the following description from which yet other objects and advantages will be apparent. The description to follow is presented in light of the drawings forming a part hereof, and in which drawings like reference numerals indicate like parts.

FIG. 5 is the plan of a paperboard blank cut and scored to form a display holding assembly; and

FIG. 6 is a plan view showing the manner in which the elements of FIGS. 4 and 5 are bound together into a unitary structure.

By reference to FIGS. 1 and 2, it can be seen that the mount illustrated therein includes a display supporting assembly consisting of a display mounting section 10 in combination with a supporting prop section 12, and a display holding assembly 14 which is hinged to the display supporting assembly.

The construction of the mount herein can best be understood by reference to the method by which it is made and for the purpose of explaining the method reference is first made to FIGS. 3 through 6.

The supporting prop section 12 and the display mounting section 10 of the display supporting assembly are formed from a rectangular blank of paperboard, as shown in FIG. 3. Resort is had to a single die cutting and scoring operation to divide the blank into sections which are foldable upon themselves. Thus, a weakened hinge line 16 is formed transversely of the blank and'this hinge line divides the blank into the display mounting section 10 and the supporting prop section 12. The display mounting section 10 is transversely scored along a line 18 which divides the display mounting section 10 into a display mounting face panel 20 and a display mounting back panel 22. The panels 20 and 22 arepreferably of equal size, such that when they are folded into face-toface contact with each other upon the score line 18, the free edge of the display mounting face panel 20 will coincide with the edge of the display mounting back panel 22 at the hinge line 16. l

The supporting prop section 12 is likewise divided into two equal parts by a transverse score line 24. This score line divides the supporting prop section into a supporting prop back panel 26 and a supporting prop face panel 28. When the supporting prop face panel 28 is rotated about the score line 24 to bring it into face-to-face contactwith the supporting prop back panel 26, its free edge will coincide with the edge of the supporting prop back panel 26 which defines the hinge line 16.

The hinge line 16 is preferably in the form of an inter rupted transverse slot, as shown in FIG. 3; the display mounting section l0 and the supporting prop section 12 being connected across the slot 16 by means of a pair of ribs ill and 32. The central portion of the hinge slot 16 is in the form of a T which, at the base thereof, has formed a hinge plate holding tongue 34. The hinge plate holding tongue is adapted to rotate on a score line 36 and it is designed to engage one edge of a hinge plate 38 of ductile material, as shown in FIG. 3. The ductile hinge plate 28 may be of any suitable material which will bend readily and which is form-retaining. A thin plate or sheet of aluminum or tin is suitable for the purpose.

After the blank is formed, as stated, in respect to the description of FIG. 3, the ductile hinge plate 38 is positioned on the blank such that it spans the hinge slot 16 and has one edge thereof engaged under the hinge plate holding tongue 34. The hinge plate holding tongue 34 holds the hinge plate 38 in position as the blank is further manipulated in the fabricating process. The pressure with which the hinge plate holding tongue 34 grips the I hinge plate 38 can be determined and regulated by the nature of the score line 36. It is preferred that the score line 36 merely be press-creased into the paperboard in order to retain a maximum amount of resilience in the tongue and, therefore, a tongue which will bear upon the plate with a substantial pressure.

After the hinge plate 38 has been assembled with the blank as described, the display mounting face panel 2th is folded upwardly on the score line 18 such that it overlies the bottom half of the hinge plate. Simultaneously therewith the supporting prop face panel 2b is folded downwardly on the score line 24 such that it overlies the upper portion of the hinge plate. The folded structure at this point may be bound together by means of a binding material 46 which is adhesively attached to the face or the folded blank, extends about the edges thereof terminates on the rear face of the blank. The terminal edges of the binding material may then be covered by a liner 4?... The mount supporting structure, as thus constituted, is flat and in such condition that it can be easily handled in storage and transit. In order to erect the structure, it is merely necessary to rotate the supporting prop section 12 rearwardly in respect to the display mounting section lit, as shown in FIGS. 1 and 2. The act of rotation bends the ductile hinge plate 38 such that the supporting prop section 12 is self-sustaining. The hinge slot 16 constitutes a guide which insures that the hinge plate will be bent along a straight, sharp line.

. The supporting structure may be employed as such by incorporating into or attaching to the face of the display mount section whatever material is to be displayed, e.g., a calendar pad or print. A desirable commercial embodiment of the display mount will, however, include the display holding assembly 1- 3. The elements of a suitable display holding assembly are illustrated in FIG. 6, wherein it can be seen that it is constructed from a rectangular blank of. paperboard stock which is transversely scored to divide it into three equal sections. Thus, parallel score lines 44 and 46 are formed across the faceof the blank. The score line 44 forms a face board 48 between it and the bottom edge of the blank, while the Score line 46 forms a backboard 50 between it and the upper edge of the blank; between them the score lines 44 and 46 define an intermediate board 52. As the blank is being scored, a display Well 54 is also formed in the intermediate board 52. This well is formed by cutting out a section of the intermediate board along an outline generally corresponding to the outline of the display material'designed to be carried therein. The method for forming display Wells and windows, disclosed in my United States Patent 2,355,706, issued August 15, 1944, as Well adapted to the formation of the display well 54 and the display window which is subsequently formed.

After the blank of FIG. 6 has been scored and cut, as described, the face board 48 is rotated inwardly on the score line 44, to bring it into back-to-back contact with the intermediate board 52, and the back board is rotated upwardly about the score line to bring it into face-to-face contact with the intermediate board 52.

The folded blanks of P165. 3 and 5 are then aligned with each other such that the edge of the display supporting assembly, which is formed at its fold line 1%, is slightly spaced from the edge of the display holding as sembly which is defined by its score line as; the display holding assembly'being turned with its back board 59 uppermost, all as shown in FIG. 6. The binding mate: rial 40 is now applied to the normally exposed face or the assemblies such that it spans the gap between themv As described in relation to the finishing operation on the display supporting assembly, the binding material is adhesively attached to the face of the display supporting assembly and the display holding assembly, and it is turned about the edges of the assemblies and terminates on the back faces thereof. The exposed edges of the binding material on the back face of the assemblies are then preferably covered by applying the liner 4 2, as in the case above described. After the binding material as has been applied, a display window 56 (shown in dotted lines in FIG. 5) may be cut through the binding material and through the face board 48 to form the display window.

The binding material it and the liner &2 now constitute a hinge between the supporting structure and the display holding assembly. This hinge connection allows the display holding assembly 14 to be folded upwardly into contact with the display mounting section lib, as shown in FIG. 2. In this position, the display material in the display well 54, e.g., a calendar pad or print, can be viewed from the face of the mount. it is contemplated that the lining material 42 be provided for the inscription of telephone numbers, anniversary dates, and the like. These notations are, therefore, readily accessible upon rotation of the display holding assembly 14 on its hinged connection with the display mounting section ill.

The mount can be erected into display position with the greatest of ease merely by rotating its supporting prop section on its hinge line 16 such that it will be disposed approximately perpendicular to a supporting surface. The ductility of the hinge plate 38 will maintain the supporting prop section in its adjusted position. In FIG. 2, the supporting prop section 12 is rotated downwardly such that its free end is adapted to contact the supporting surface. In this case, the display mounting section and the display holding assembly will be in back-to-back contact with each other. On the other hand, the supporting prop section 12 may be rotated inwardly such that its free end engages the under surface of the display holding assembly. In, this case, the display mounting section ll) will be in contact with the mount supporting surface. 1

The. horizontal panel of the face board .8 which is disposed above the display window 56 can be imprinted with an advertising message or the like.

While the novel features of the invention have been illustrated and described in connection with a specific embodiment of the invention, it is believed that this em: bodiment will enable others skilled in the art to apply the principles of the invention in forms departing from the exemplary embodiment herein, and such departures are contemplated by the claims.
